I've never been to a rallycross before but I've been told that it is basically an autocross on dirt. You probably don't want to compete if you care about your paint, are lowered, or have low profile rubber but other than that any street legal car in acceptable condition is fair game. I know they will probably be really picky about wheel bearing play and tire tread.

I've heard as many as 100 cars might be competing from some people that have attended prior events. I'm really excited this will be so close to home for a change!

And yes, rallycross is basically a autocross on dirt. They usually just take a field of some sort and mark it out with cones just like in autocross. You'll earn points even as a casual driver. They just don't matter if you don't plan on going to other events.

Do you have a 81' coupe or hatch? I really, really want to find an 81' coupe. For some reason I really like those cars. I think they would make a great rally car and are only a few years away from being eligable for the Vintage class in performance rally...
